No tingly feeling today, normal?!

Hello ladies! My fiancé and I were trying to conceive for 8 months when we got our first BFP. According to this app, I am 7w2d. Yesterday I felt sick and extremely tired with some tingling sensation in my stomach. Today I feel fine (other than sore breasts) with no more tingling sensation. Is this normal? I had a miscarriage about 4 years ago and hope I won't have to go through that again. Anyone having similar symptoms, or know if this is normal??
